Hi,
When it is working properly, the user who is disconnected and try to reconnect again , dude is staying in connecting mode. But when I check the CHR logs there is no connection request.
I can’t login over 8291 via winbox connection when this happens. It looks like the 8291 doesn’t getting any new connection. if anybody who have this problem or knowledge, I’m waiting for help.
Thanks.
my problem is similar but worst 
.
Installed dude and the directory and the package not exists.
what could happened?
I tried many times!
RB750G3
From the wiki:
Overview
New hEX (RB750Gr3) unit is ideal for small to medium size The Dude server installations. For server database storage on this device you have two options: MicroSD cards or USB flashes.
Note that preferably you should use industrial grade mircoSD cards and USB flashes as they have longer life cycle under applications that can write data to flash more frequently as The Dude server database in this case. Note that you still use standard usb flashes and microSD card they just won’t last as long as Industrial grade counterpart would in long term use.
I’m guessing you following the steps https://wiki.mikrotik.com/wiki/Manual:The_Dude_v6/The_Dude_server_on_hEX_RB750Gr3 right ?
Oh my god the problem was really lame..
The dude server installer name contained special character because it was the second download from the sam efile. I deleted from the name “(1)” than it worked fine… But there is still problem with the sd cards sometimes it identify to disk 1 sometimes disk 2 then i have to change the disk in dude settings and runs well.
+++ in this situation /user print command not working on cli (6.43 has the same problem)
